Struct PaymentQuote

pub struct PaymentQuote {
    pub content: XorName,
    pub timestamp: SystemTime,
    pub quoting_metrics: QuotingMetrics,
    pub rewards_address: Address,
    pub pub_key: Vec<u8>,
    pub signature: Vec<u8>,
}

A payment quote to store data given by a node to a client Note that the PaymentQuote is a contract between the node and itself to make sure the clients aren’t mispaying. It is NOT a contract between the client and the node.

Fields

content: XorName

the content paid for

timestamp: SystemTime

the local node time when the quote was created

quoting_metrics: QuotingMetrics

quoting metrics being used to generate this quote

rewards_address: Address

the node’s wallet address

pub_key: Vec<u8>

the node’s libp2p identity public key in bytes (PeerId)

signature: Vec<u8>

the node’s signature for the quote

Implementations

impl PaymentQuote

pub fn hash(&self) -> QuoteHash

pub fn bytes_for_signing( xorname: XorName, timestamp: SystemTime, quoting_metrics: &QuotingMetrics, rewards_address: &RewardsAddress, ) -> Vec<u8>

returns the bytes to be signed from the given parameters

pub fn bytes_for_sig(&self) -> Vec<u8>

Returns the bytes to be signed from self

pub fn peer_id(&self) -> Result<PeerId, EvmError>

Returns the peer id of the node that created the quote

pub fn check_is_signed_by_claimed_peer(&self, claimed_peer: PeerId) -> bool

Check self is signed by the claimed peer

pub fn has_expired(&self) -> bool

Returns true if the quote has expired

pub fn is_newer_than(&self, other: &Self) -> bool

Check whether self is newer than the target quote.

pub fn historical_verify(&self, other: &Self) -> bool

Check against a new quote, verify whether it is a valid one from self perspective. Returns true to flag the other quote is valid, from self perspective.

Trait Implementations

impl Clone for PaymentQuote

fn clone(&self) -> PaymentQuote

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PaymentQuote

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PaymentQuote

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for PaymentQuote

fn cmp(&self, other: &PaymentQuote) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PaymentQuote

fn eq(&self, other: &PaymentQuote) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PaymentQuote

fn partial_cmp(&self, other: &PaymentQuote) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PaymentQuote

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
